ObjectiveTo establish a prognostic score model based on preoperative neutrophillymphocyte ratio (NLR) to predict recurrence of hepatocellular carcinoma (HCC) following liver transplantation.MethodsThe clinical data of 76 HCC patients undergoing liver transplantation were retrospectively analyzed.An NLR≥2.5 was considered to be elevated.A preoperative recurrence score was established by using three preoperative factors which significantly increased the risk of tumour recurrence after liver transplantation on multivariate analysis,namely,vascular invasion,tumour number＞3,and NLR≥2.5.We then evaluated the scoring system in predicting tumour recurrence of HCC after liver transplantation.ResultsArea under the receiver operating characteristic curve of preoperative recurrence score was 0.758,with scores of 2 and 3 having hazard ratios of 10.038 and 59.773,respectively.All ten patients with a score of 3 developed tumour recurrence in less than 6 months.The 1-,3- and 5-year tumour-free survival rates for patients with a score of 0,1 and 2 were 95.0％,78.4％,and 78.4％ vs.76.9％,66.9％,and 63.2％ vs.51.9％,8.7％,and 8.7％,respectively.Of 55 patients who had no gross vascular invasion,5 patients with both tumour number＞3 and NLR≥2.5 developed recurrence in less than 31 months.ConclusionsPatients with both preoperative NLR≥2.5 and tumour number more than 3 were at a high risk of tumour recurrence after liver transplantation for HCC.The preoperative recurrence score model strongly correlated with tumour recurrence,and may aid in the selection of patients with HCC for liver transplantation.

BackgroundResearches found that the posterior capsular opacification (PCO) after lensextraction is associated with the elevation of the transforming growth factor-β(TGF-β).To seek the drug for inhibitingproliferation of lens epithelial cells (LECs) is crucial in the treatment and prevention of PCO.ObjectiveThisstudy was to investigate the preventing effects of decorin on the proliferation of LECs.MethodsRabbit LECs wascultured and passaged.The LECs in growth phase were incubated in 96 well plate at the density of 8×106/L.Decorinwith the concentrations 0.1,1.0,10.0 mg/L was added into the medium for 24,48 and 72 hours respectively.0.1％DMSO was used at the same way as positive control group,and the regular cultured cells worked as blank controlgroup.The inhibitory rates of different concentrations of decorin on the growth of LECs were detected by MTT at 24,48and 72 hours after addition of decorin.The percentage of LECs in different cell cycles in various groups was assayedusing flow cytometry.TGF-β level in medium suspension was detected using ELISA.The expression of TGF-β mRNA in LECs was checked by RT-PCR,and α-SMA expression in LECs was determined using immunochemistry.Results ELISA assay showed a statistical difference in the TGF-β levels of different groups (F=39.24,P=0.03 ).The TGF-β levels in 1.0,10.0 mg/L decorin groups were significantly decreased in comparison with blank control group (P＜0.01) and 0.1 mg/L decorin group (P＜0.05 ).The inhibitory rates of decorin in the concentrations of ≥ 1.0 mg/L on the growth of LECs were higher than the blank control group,and those in various concentrations of decorin groups were considerably lower in 24 hours compared with 48 and 72 hours ( P＜0.05 ) and so was the 48 hours compared with 72 hours (P＜0.05 ).The percentages of LECs in G0/G1 phase were ascent in 0.1,1.0 and 10.0 mg/L decorin groups in comparison with G2/M and S phase (P＜0.05).Immunochemistry revealed the weak expression of α-SMA in various decorin groups in comparison with control group. Conclusions Decorin can effectively inhibit LECs growth and induce LECs apoptosis in concentration- and time-dependent manner.It is suggested that decorin can be used in the prevention and treatment of after cataract.

OBJECTIVETo investigate the efficacy of Chinese medicine Huangban Bianxing Recipe (HBR) for treatment of choroidal neovascularization (CNV).

METHODSEighty patients (97 eyes) suffered from CNV were assigned to two groups, the treated group treated by HBR orally taken one dose every day and the control group treated with ginkgo leaf tablet 1 tablet (19.2 mg) thrice a day, all for 3 months. The best corrected visual acuity (BCVA), fundus hemorrhagic area were measured; the neo-genetic vascular leakage area determined by fluorescent fundus angiography (FFA); and the out-layer high reflective band thickness (OHRBT) estimated by optical coherent tomography (OCT) were recorded before and after treatment.

RESULTSAfter treatment, in the treated group, BCVA was improved, with an effective rate of 67.12%, while in the control group, it was 33.33%, the former was better than the latter significantly (P < 0.05). The effective rate in reducing fundus hemorrhagic area in the two groups (85.11% vs 47.62%) and that in the CNV closure showed by FFA (67.50% vs 37.50%) were also superior in the treated group (P < 0.05). Besides, OCT showed that the OHRBT reduced significantly after treatment in the treated group (P < 0.01).

CONCLUSIONHBR can improve the vision, reduce the CNV leakage in the macular region, and advance the absorption of fundus hemorrhage in CNV patients.

Objective To evaluate the value of fMRI guided brain surgery for the lesions in or around Broca's area.Methods Forty-three patients with lesions in or adjacent to the Broca's area were studied.fMRI imaging was obtained by BOLD technique with the tasks of reciting.Fiber tract imaging of white matter was obtained by DTI technique.All functional imaging and anatomic imaging were transferred to neuronavigation system.The technique of direct cortical stimulation was used to validate the language cortex in fMRI.The lesions were resected in microscope.Results Broca's area activation was detected in 38 cases..The distance between the fMRI peak and direct cortical stimulation was rated as overlapping (<1 cm diatance) in 25 cases and neighbouring (<2 cm diatance) in 11 cases.Total lesion resection was achieved in 17 cases, subtotal resection in 14 cases, and partial resection in 12 cases.Postoperative neurological functions were improved in 8 cases, unchanged in 31 cases, and temporary worsen in 4 cases.Conclusions The identification of the Broca's area by reciting task in fMRI is sensitive and precise.The fMRI is helpful to decrease the side effect injury in the brain surgery for the lesions in or around the Broca's area.

ObjectiveTo study the role of micafungin in the treatment of invasive fungal infection after liver transplantation.MethodsWe retrospectively studied the clinical data of 32 patients who developed invasive fungal infection after liver transplantation treated in our center between December 2008 and June 2010.The therapeutic effect,adverse effect,and the blood concentration/dose ratio of tacrolimus (tacrolimus concentration per dose.kg-1) before and after micafungin treatment were analysed.ResultsThe curative rate was 93.7％.There were no obvious toxicity and sideeffect.The blood concentration/dose ratio in the triazoles treatment group [(1031± 634.2) ng·ml-1/mg · kg-1] was markably higher than the micafungin treatment group [(172.6±39.45) ng·ml-1/mg · kg-1] and the control group (ceasing antifungal agents) [(183.8±47.08) ng· ml-1/mg · kg-1] (P＜0.05).However,there was no significant difference in the blood concentration/dose ratio between the micafungin treatment group and the control group (P＞0.05).ConclusionsMicafungin did not significantly affect the blood concentration/dose ratio of tacrolimus,and effectively treated invasive fungal infection in patients after liver transplantation.

ObjectiveTo investigate the choice of graft,and transfusion and immunosuppressant regimen of a RhD negative recipient in liver transplantation.MethodsOne RhD negative patient with hepatocellular carcinoma who received a liver graft from a RhD positive donor was retrospectively studied,and related references were reviewed.During the operation,the patient received five units of RhD negative/O RBC,3000 ml positive/O plasma and 30 units cryoprecipitate.Tacrolimus and prednisone were used to prevent rejection,and prednisone was withdrawn 30d post transplant.Results The patient's liver function recovered smoothly,without any acute rejection or hemolytic reaction.Anti-D antibody was not detected.The patient suffered from cancer recurrence 9 months and died of brain metastasis 13 months after transplantation.ConclusionsA RhD negative recipient can receive a graft from a RhD positive donor in liver transplantation.The selection of RBC and platelet from RhD negative or positive donors should be based on the result of anti-D antibody test.Plasma and cryoprecipitate can be transfused regardless of Rh type.Enhanced immunosuppressant regimen was unnecessary for these patients.

Objective To evaluate the correlations of vascular structures,hemodynamic changes and recanalization before receiving carotid endarterectomy ( CEA) in patients with subtotal or complete occlusion of carotid artery using color Doppler flow imaging (CDFI) and transcranial Doppler (TCD) ultrasonography. Methods A total of 107 patients were diagnosed as subtotal ( stenosis rate 95% to 99%) or complete occlusion of carotid artery with DSA and treated with CEA at Beijing Xuanwu Hospital, Capital Medical University from January 2005 to January 2014 were enrolled retrospectively. The mean age of patients was 61 ± 9 years. According to the findings of DSA,they were divided into either a carotid artery subtotal occlusion group (n=63) or a complete occlusion group (n=44). The vascular diameter,the locations of the lesions ( internal carotid artery or common carotid artery) ,the lumen echo characteristics,and whether internal-external artery collateral circulation patent or not at different stages in patients of both groups were documented. Results The lumen diameter of distal segment was significant wider in patients of the complete occlusion group compared with the subtotal occlusion group (4. 1 ± 1. 1 mm vs. 3. 2 ± 0. 8 mm). There was significant difference between the 2 groups (P <0. 01). There was no significant difference between the location of occlusion and the recanalization rate (P=0. 460). The recanalization rate of the lumen homogeneous echo ( hypoecho and echodense) filling patients (94. 1% vs. 86. 7%) was significantly higher than that of the patients of heterogeneity echo. In patients with complete occlusion of internal carotid artery,the recanalization of CEA would increase when the internal-external collateral arteries were patent. For general comparison,the recanalization rate of the subtotal occlusion group was significantly higher than that of the complete occlusion group (P<0. 01). Conclusion The carotid artery diameter normal or broadening ,the homogeneous echo in the occlusive lumen and the internal-external collateral arteries patency are closely associated with the recanalization rate. The preoperative ultrasonography has great value for the assessment of recanalization of carotid artery occlusive disease after CEA.

Objective To explore the changing rules of schistosomiasis infection and Oncomelania hupensis snail situation in areas where schistosomiasis transmission was controlled or interrupted or transmission rebounded after the interruption. Meth-ods Daye City,Wuxue City and Jingshan County were selected and investigated retrospectively to collect the schistosomiasis epidemiological information 10 years before they reached the criteria of transmission controlled and the subsequent years until 2008. The database of retrospective investigation was established for analyzing the trends and rules of the changes of snail status and human infection status. Results In Daye City,there was no snail areas and schistosomiasis patients and cattle after reach-ing the criteria of transmission interrupted in 1987. The infection rate of residents were positively correlative with the infection rate of cattle and snail areas(r=0.865,0.843,P<0.01). In Wuxue City,the proportion of snail areas occupying the historic snail areas kept a steady from the transmission controlled to transmission interrupted,but it began to rebound to the highest level in the history(8.93%)after the transmission interrupted for 3 years. In Jingshan County,the infection rates of residents and cat-tle were all stable from 1%to 2%after the transmission controlled. The proportion of snail areas occupying the historic snail ar-eas was rebounded from 1.63% in 1985 to 21.50% in 2008,and the densities of living snails rebounded from 2005. Conclu-sions The infected snails could be the sensitive indicator of the rebound of snail situation and human infection. The elimination of schistosomiasis still depends on the control of snail areas,including strengthening the infected snail control.

Objective To evaluate the feasibility and effectiveness of combination chemotherapy with etoposide and cisplatin(EP)regimen on the patients with high-risk,chemorefractory and recurrent gestational trophoblastic neoplasia(GTN).Methods Thirty-nine patients with gestational trophoblastic tumors were analyzed retrospectively,25 of 39 patients were of high-risk,9 patients were chemorefractory and 5 patients were recurrent.All 39 patients were administrated with EP regimen,and 10 patients were assisted with surgery.All the patients were followed up.Clinical response,toxicity,the occurrence of secondary tumors of all patients,and the fertility of 30 patients whose fertility function was preserved were investigated. Results Thirty-nine GTN patients underwent a total of 221 cycles of the EP regimen.The average number of courses for each patient was 5.7.The total complete remission rate of the regimen was 74%(29/39). Twenty-five patients with high-risk GTN received a total of 139 cycles and the average number of courses was 5.6.Nineteen patients achieved complete remission and 6 patients showed drug-resistant.The complete remission rate of the high-risk group was 76%(19/25).Nine patients with chemorefractory GTN obtained a total of 55 cycles and the average number of courses was 6.1.Six patients achieved complete remission and 3 patients showed drug-resistant again.The complete remission rate of the chemorefractory group was 6/9. Five patients with recurrent GTN received 27 cycles and the average number of courses was 5.4.Four patients achieved complete remission,1 patient showed drug-resistance and died.Bone marrow toxicity, gastrointestinal reaction and alopecia were the main side effects of the EP regimen,but the bone marrow toxicity was slight and no grade Ⅳ side effect occurred.No fatal effect was found.Eight of 30 patients whose fertility faction was preserved had become pregnant after recovery,with a total of 8 pregnancies.Among them,2 were terminated by induced abortion,and 6 underwent normal term delivery and gained 6 infants who had no congenital malformation.All the 6 children had normal growth and development after childbirth. None of the women developed secondary tumors.Conclusion The EP regimen is effective and safe for the treatment of high-risk,chemorefractory and recurrent GTN.
